by ribs 23. The inner and outer wall members 21 and 22 are slotted asindicated at24 to receive the pivot pin 13.

The cap portion 15 is covered by the outer cover or cap member 14.Thecap 14 is of inverted cup shape, and the edge or skirt of the outercap 14 is peened under a shoulder 27 on the cap of the body to form alipwhich engages the shoulder so that the inner and outer caps are firmlysecured together. The cap 14 is formed of metal or other rigid material.The pivot pin 13 projects through openings 28in the outer cap 14 andthrough the slots'24 of the inner or body cap 15. V

The clamp member 12' is pivotally 'mounted on the pivot pin 13. Theclamp member12 has a trough-shaped skirt 31, provided with a flange 32,for gripping the bottle neck at the bead 33 thereof to secure theclosure to the bottle, as indicated in Fig. 2. Finger grips"34.areprovided at opposite edgesrof the trough-shaped skirt for use inswinging the clamp member into and out of engagement with the bottleneck.

The device illustrated in Figs. 4 and'S includes a onepiece body 35, aclamprnember 36, a pivot pin 37, 2. pivot pin support plate 38 and anouter cap 39.

for. securing a clamp member which is adapted to hold the capflange inengagement with the lip.

From the following description and the accompanying drawing, the aboveand other objects and features of the invention will be apparent tothose having ordinary skill in the art to which it pertains.

In the drawing:

Figure 1 is a perspective view showing a bottle provided with a closuremember constructed in accordance with an embodiment of this invention;

Fig. 2 is a view in transverse section of the bottle and closure memberillustrated in Fig. 1;

Fig. 3 is an exploded viewof the closure member shown in Figs. 1 and 2;

Fig. 4 is a view in transverse section showing a bottle and'a closuremember constructed in accordance with another embodiment of thisinvention; and

pin 13, and an outer cap member 14. The body is formed of a polyethyleneresin material or other suitable deformable elastomeric material. Thebody includes a cylindrical cap portion 15 having a flange 16 whichoverlies the lip of the mouth of a bottle 17 (Fig. 2) and a cylindricalhollow plug 18 which fits inside the mouth of the bottle. The inner orlower end of the plug is closed by an inner wall 19 while the outer orupper end of the plug is open. As shown, the wall 19 is bowed inwardlyof the bottle.

The plug portion fits tightly within the neck of the bottle 17 asindicated in Fig. 2, and pressure inside the bottle causes the walls ofthe plug portion to expand and firmly engage the interior of the bottle.

As shown in Fig. 1, the upper portion of the cap 16 of the body includesspaced inner and outer wall members indicated at 21 and 22,respectively, which are separated The body 35 is formed of rubber or thelike and, as shown in Fig. 4, has a bottle-shaped opening 41 in a loweror plug portion 42 thereof. The plug portion has a constricted neck orgroove 43 adjacent an upper or cap portion 44. The plate 38 rests on topof the plug portion and inside a bore 46 in the cap portion of theclosure member. A diametrically extending groove 47 in the plate 38receives the pivot pin 37. The outer cap 39 a the inner cap to securethe inner and outer caps together.

The clamping member 36 is similar in construction ,to the clampingmember of the device illustrated in Figs.

1 and 3, and clamping member 36 is pivotally mounted on the pivot pin 37and can swing into engagement with the bead 51 at the neck of the bottle52 to hold the closure member with the flange 53 of the inner capportion firmly in engagement with the lip of the mouth of the bottle.

Pressure inside the bottle 52 forces the wall of the portion of the plug41 inboard of the groove 43 firmly into engagement with the neck of thebottle to form a seal between the plug and the inside of the bottle. Asecond seal is formed where the flange 53 engages the lip of the bottle.

Each of the devices illustrated in the drawing and described aboveprovides a firm double seal including a seal at the flange ofthe innercap portion and a second'seal between the plug portion and the interiorof the neck of the bottle. V

Having described my invention, what I claim as new and desire to secureby Letters Patent is:

1. A closure for a bottle comprising a member of elastomeric material,said member having a hollow plug closed at its inner end and open at itsouter end, and a cap integral with the plug, said cap having a flangeadapted to engage flush with the lip of the mouth of the bottle, asecond cap disposed over the first cap, the second cap having a skirtthat is peened under the first cap to secure the same thereto, a'clampmember for said closure and a one-piece pivot pin projectingtransversely of the caps above the bottle-engaging flange and projectingthrough the sides of the clamp member for pivotally securing the clampmember to the first and second caps and locking the hollow plug adaptedto'be received in the neck of a bottle I and'a cylindrical cap portionfor overlying the mouth of thebottle, the cap portion having an axialbore in the end thereof remote from the plug, a plate received in saidbore, said plate having a diametrically extending groove, an'inverted'cup-shaped member of rigid material overlying'the sides of thecap portion and the end of the cap portion remote from the plug, aninwardly turnedlip on the edge of the cup-shaped member, there being ashoulder on the cap portion engaging said lip to hold the cup-shapedmember firmly in position on the cap portion, a pivot pin received inthe groove of the plate and projecting through the sides of thecup-shaped member, and a U-shaped member pivotally mounted on said pivotpin, there being a flange'on' the U-shaped member remote from the pivotpin and engageable with the bead at the mouth of the bottle tolock thecap portion against the mouth of the bottle, the plug portion .beingdeformable by pressure inside the bottle to firmly engage the inside ofthe neck of the bottle. A removable closure for a bottle which comprisesa one-piece body of elastome'ric material comprising a 20 hollow plughaving an annular wall for engaging the inside a of the neck of thebottle and an integral end wall, and

an annular cap portion of greater diameter than the plug Iintegrallyformed withthe open end of the plug, said cap portion having abottle-engaging flange adjacent the plug and a shoulder spaced from thebottle-engaging flange, a rigid cover member overlying the sides and theend of the cap portion remote from the plug, there being an inwardlyturned lip on the edge of the cover member engaging said shoulder tohold the cover member and the cap portion in assembled relation, aone-piece pivot pin projecting transversely of the cap portion and thecover member and through the sides of the cover member above thebottle-engaging flange to lock the cover member and the cap portionagainst relative turning, and a U-shaped member pivotally mounted onsaid .pivot pin, there being a flange on the U-shaped member remote fromthe pivot pin and engageable with the head at the mouth of the bottle tolock the cap portion against the mouth of the bottle.
